Literature reveals very devoid regarding dental anxiety in the brazilian population. The purposal of this study was to evaluate the dental anxiety expressed among pacients undergoing dental treatment at the University of Fortaleza, Ceará, Brazil, considering social parameter, past dental experience, time of last visit to dentist, and tooth related simptoms. A total of 300 individuals (150 male and 150 female) selected at random responded to a questionary containing the dental anxiety scale (DAS) and to questions about their socio-economic level and their behavior with respect to dental treatment. The mean DAS score for the sample was 11,65±0,15 (11,8±0,21 for women and 11,5±0,21 for men). Individuals with scores of 15 or more were considered anxious, and their prevalence in the sample was 18%. Comparision of normal and anxious individuals showed that there was no difference in their distribution in relation to educational level or monthly family income, but that anxious individuals avoid dental treatment more frequently either by failing to appear for their visits or looking for a dentist after longer periods of time.A literatura mostra-se muito carente a respeito da ansiedade odontológica na população brasileira. A proposta deste estudo foi a de avaliar a ansiedade expressada entre pacientes, selecionados aleatoriamente, que estavam sendo submetidos ao tratamento odontológico na Clínica Integrada da Universidade de Fortaleza, Ceará, Brasil. Foram respeitados os parâmetros sociais e a história dental pregressa. Trezentos pacientes (150 homens e 150 mulheres) responderam a um questionário contendo a Escala de Ansiedade Odontológica (DAS) e questões de aspectos sócio-econômicos e do comportamento deles frente ao tratamento odontológico. Experiência em tratamentos, momento da última visita ao dentista e presença de sinais e sintomas foram levados em consideração. A partir dos resultados obtidos o escore médio da DAS para a amostra foi de 11,65±0,15, sendo 11,8±0,21 para as mulheres e 11,5±0,21 para os homens. Indivíduos com escores de DAS maior ou igual a 15 foram considerados ansiosos, sendo a prevalência na amostra de 18%. Conclui-se que: a comparação entre indivíduos normais e ansiosos mostrou não haver diferença na distribuição deles relacionada à escolaridade e renda familiar. Entretanto, os indivíduos ansiosos mais freqüentemente evitam o tratamento odontológico, quer seja faltando às consultas ou procurando o cirurgião-dentista após períodos de tempo mais longos

Seal capability of interim post and core crown with temporary cements

The purpose of the present study was to evaluate the in vitro seal capability of interim post and core crown restorations. Eighty teeth were selected and divided into 8 groups. Four experimental groups received interim posts and core crowns. Half of each group was decoronated at the cementum-enamel junction, groups PCCH and PCZO. The other half was sectioned 2 mm coronal to the cementum-enamel junction, groups PCrZO and PCrCH. The interim post and core crowns were luted with Rely X Temp NE, groups PCrZO and PCZO; Hydro C was used for Groups PCrCH and PCCH. The control groups, PC and PCr, received uncoated post and core crowns; groups OTg and OT were left without interim post and core crowns and were totally open. Infiltration was accessed by dye exposure followed by demineralization of the teeth. The length of the infiltration was measured using digital images taken from the specimens. The images were inserted into the Image Tool 3.0 software. Kruskal-Wallis analysis of variance and Dunn's multiple comparison method were used to test for significant differences among test groups (P < .05). Groups PCrZO and PCrCH showed the least dye penetration, followed by groups PCZO and PCCH. Teeth restored with interim post and core crowns will be subject to leakage. Ethics Committee: 095/2008
